User USB connector

STK600 has a USB connector that target AVR devices with USB interface can utilize. The connector is a mini-AB connector that supports On-the-go functionality. The routing card for the device connects the USB connector to the appropriate pins on the AVR.

VBUS Generation

When the target AVR is acting as an On-the-go master it must supply VBUS voltage to the USB device it is controlling. To do so, place a jumper on the pin header (J901) next to the USB connector. The FET is controlled by the UVCON signal, also routed to the target AVR.

When not using the VBUS generation feature, the jumper must be removed.

Note: VCC is 5.3V
